Forum Notifier alerts you when it sees a new post of a user quoting you on a supported forum. The supported forums are polled once a minute, meaning you should receive a notification within a minute of the post.

Even though it doesn't seem to be getting much interest on this forum, I've been working on converting the script to support multiple forums. While doing this I used DroidForums to test. I think I have everything working(easier to add new forums in the future as well)... but I'm going to let it run for a night at least.
